To all whom it TIZ/(I/Z/ concern.-

Be it known that I, IRVING STANLEY, a citizen of the United States, residing in the borough of Manhattan, in the county of New York and State of New York, have invented a new and useful Improvement in Bread or Dough Mixers, of which the following is a specification.

This invention is designed to furnish an eflective and economical construction for a dough or bread mixer; and, among other things, it provides an article of this character with features ofadjustment that enable it to be easily and quickly applied to the vessel in conjuction with which it is to be used.

As illustrated, the mixer embodies a structure intended to be used as an attachment for application to a pan or other receptacle, the particular features of the invention residing in the inexpensive construction and means whereby it is adapted to be readily mounted upon receptacles of different sizes.

A further feature of the invention relates to means for holding the receptacle, together with the attachment mounted thereon, upon a table or other support with rigidity suflicient to permit the mixing operation to be effectively performed.

The mixer embraces a bridge member adapted to be supported upon opposite sides of the receptacle. This member may beneficially be adjustable to adapt it to vessels of different diameters, and for the sake of cheap ness it may be formed of reversely-bent wires or rods having at their ends catches or keepers adapted to fit over the edges of the recep' tacle. The bridge member supports a bearing-piece for the shaft of the stirring-arm, this shaft being preferably capable of adjustment depthwlse of the receptacle. This shaft is secured to a hand-crank. Means are provided for holding the shaft and crank against longitudinal movement relative to the bearing-piece, at the same time leaving the parts free for rotation and ready adjustment. The bridge member is suitably formed to engage with a holding-down device, which is constructed and arranged in such manner that it may be conveniently slipped on a corner of the table to hold down one end of the bridge member or the receptacle to which it may be attached. This with the pressure of the hand of the operator on the opposite side of the apparatus suffices to retain the parts against displacement during the mixing operation. Preferably, also,

the arm carries an adjustable auxiliary arm whereby the effective length of the mixingarin may be altered.

In the drawings accompanying the present specification, Figure 1 illustrates a perspective view of a mixer embodying the present improvements, the receptacle or dough-pan and a part of a supporting-table being shown in dotted outline. Fig. 2 illustrates a plan view of the bridge member of Fig. 1, the operating-handle and mixing-arm shaft being removed and, the dotted lines at the ends indicating the longitudinal extensibility of the bridge member. Fig. 3 illustrates a crosssectional view, the scale of this figure being somewhat larger than that to which Fig. 2 is drawn. Figs. 4 and 5 illustrate views similar to Figs. 2 and 3, respectively, but showing a modified construction. Figs. 6 and'7 illustrate plan and edge views, respectively, of a modified construction for retaining the relatively-adjustable mixer-arm shaft and operating-handle against longitudinal movement when affixed one to the other. Fig. 8 is an elevational view of the mixer-arms and their shaft, showing the ad ustable auxiliary mixerarm. Fig. 9 illustrates a view looking from the left of Fig. 8.

Similar characters of reference designate corresponding parts in all the figures.

The mixer-arm is characterized by cheap and simple features of adjustment applicable for the most effective use under various conditions-such, for instance, as different quantities of dough, pans or receptacles of different diameters and depths, &c. Economy of manufacture is thus facilitated, not only by reason of simplicity of construction, but also by reason of the capacity for adjustment, for by adjustment the mixer may be made to meet a wide range of conditions.

The present mixer is essentially an attachment or appliance capable of cooperation with the ordinary an of the kitchen and is especially designed to this end, as will ap pear from the following description.

The mixer embraces a bridge member hav ing at each end a transversely-extending catch or keeper and capable of adjustment to vary the distance between these catches. Specifically the bridge member comprises two parts, each consisting of a tongue 2, made in the illustrated construction of a rod or wire bent upon itself and having its closed end turned over to form a catch or keeper 3. This bridge member supports a bearing-piece 4, in Figs. 1 and 2, or 4, in Figs. 4 and 5, for the mixer-arm shaft, the free ends of the rods constituting the bridge member being slidably mounted in openings in the bearingpiece. In Figs. 1 and 2 the rods are disposed side by side, passing through openings in the transversely-bent ends 5 5 of the bearingpiece, while in Figs. 4 and 5 the two rods of the bridge member are disposed in line with each other and located in sockets formed by the turned-in longitudinal edges 5 5 of the bearing-piece. This construction, it is evident,per1nits the hooks or catches 3 3 by adjustment to be engaged with the sides of the pan designated by B. Preferably the bridge member is inserted between the handles B B of the pan, whereupon by pushing together the parts of the bridge member the catches on the latter may be engaged with the pan edge. The parts may be firmly clamped together by means of a thumbscrew 6, which enters a tapped hole in a strap 7, extending crosswise below the bridge parts and impinging against the exposed surfaces of the rods. In the construction illustrated in Figs. 4 and 5 two such straps and thumb-.

screws are shown.

It is intended in the operation of the mixer that the pan with the mixer mounted thereon shall be held against displacement by some simple meansfor instance, one of the catches 3 may engage with a link 8, slipped over the corner of the supporting-table C, and when so held the pressure of the hand on the opposite side-of the bridge member will preclude shifting. Link 8 comprises a cross-bar 8, adapted to engage with the under surface of the table, from which cross-bar extend side members 8 8".

The mixer proper embodies one or more mixerarms carried by a shaft rotatably mounted in the bearing-piece. The parts here include an axial part or bearing-shaft 10, provided with a radial mixer-arm 10, an axial extending part 10", an offset portion 10 and a radial mixer-arm 10 In order to vary the effective length of this latter arm, the same is here provided with an auxiliary arm 11, adjustable along arm 10 and attachable thereto in its adjustable position by means such as a set-screw 11.

An operating-handle is designated by 12, and it is provided with a hub portion 12, bored to receive the axial part 10 of the shaft. Inasmuch as the depth of the amount of dough to be operated upon may vary, as well as the depth of the pan upon which. the appliance is mounted, the shaft is preferably adjustable depthwise of the pan-that is, lengthwise of the axial part 10 of the shaft. Simple means are illustrated for permitting -of this adjustment relatively of the hand crank 12 and which at the same time operates to confine the hand-crank with the ad justed and attached shaft to a rotative movement. This means comprises a laterally-extending annular lip 13, rigid with the hub portion of the hand-crank 12 and working under an overhanging part or keeper on the bearingpiece 4. This keeper consists in Figs. 1 and 2 of undercut lugs 14, extending from the upper part of the bearing-piece. To permit the withdrawal of the hand-crank from engagement with the lugs after the axial part 10 has been withdrawn from the bore of the hub portion of the arm, the lugs all he substantially on one side of a diameter, leaving the lip 13 free to be withdrawn at the opposite side.

The modified construction illustrated in Fig. 6 embraces a bearing-piece 4 of sheet metal, to which is attached a semicircular overhung flange 14, functioning in a similar manner to the retaining-lugs already described.

In assembling the mixer-arm shaft and the hand-crank the latter may be positioned by sliding the lip '13 under its keeper until the bore of the hub alines with the opening 15 in the bearing-piece, after which the axial part of the shaft may be slid into place and secured in the desired position to the crankarm 12 by a set-screw 16.
